  • Working Principle:
    • Digital closed-loop servo control with PID regulation across current, velocity, and position loops. The drive processes motion commands, compares them with motor feedback in real time, and modulates PWM output to achieve precise torque, speed, or position control. The integrated macro programming environment allows customization of motion algorithms directly within the drive firmware.
  • Installation Requirements:
    • Mount in a well-ventilated control cabinet with adequate thermal management
    • Use shielded cables for motor power, feedback, and fieldbus connections
    • Ensure proper grounding and equipotential bonding
    • Maintain minimum clearance for airflow around the drive
  • Usage Notes:
    • The “FN2” suffix indicates a specific feedback/network interface configuration — verify compatibility with the connected motor and controller
    • Common fault codes include overcurrent, overvoltage, and encoder errors — refer to the instruction manual for diagnostics
    • This is a legacy product; verify spare parts availability before procurement
